Step 5Piece by Piece (Main Line)
iImage Information

I began at one end of the pump, with the 1-1/4" valve to the 1-1/4" union. You can choose to start with other pieces, but I found that setting up the main line gave me something easy to clamp up. After the 1-1/4" to 3/4" bushing is on this tee, you can glue up the end assembly separately, and then connect it to the main assembly with the threaded 3/4" pipe.
When connecting the threaded sections, make sure to wrap some teflon tape around the threads. This will help the operation along and prevent leaks at these joints.
